Fig. 2 is a fragmentary side elevation of one side of a coke. oven battery. Since the otherside of the battery is of. like construction anddesign, it-is considered unnecessary to show-both sides and the descriptionherein'will be confined to the one side of the battery' shown on the drawings; Fig. 3 is a fragmentary. horizontal section taken on thexline 33 of Fig. 2 through two heating I Walls and an intervening coking chamber; and Fig. 4 is a fragmentary vertical section through the ends of the heating walls taken in a vertical planepassing through the line 4 4 of Fig. 3 and showing the staggered arrangement of bricks in the ends of'the heating Walls, the doors closing the ends of the coking chambers-being omitted from this figure for the sake of clarity.

Referring to the, drawings, reference numeral 11 designates a horizontally elongated coking chamber of a coke oven battery. As customary, the battery is composed of alternating coking chambers 11 and h eating .walls 12, arranged side by side in a row with crosswise extending regenerators (not shown) ,positionedbeneath'the coking chambers, parallel, thereto. The regenerators communicate with the fines in the heating walls above.- i. Each coking chamber is defined by a pair frame 1'7 is provided with alternate extending" long and short transverse ribs 22 an d 23 'respectively, and longitudinal ribs 13 which serve to reinforce a lining 24 et -refractory rnateri al.

Lining 24 is formed with a protuberant portion 26 which projects within the coking chamber and an enlarged rear portion 27 contained' withinthe channel-shaped frame 17. Recesses 28 are;dis

posed in the opposite sides of the lining 24. The side: fianges"29 iof'the door frameextend' into the recesses 28 to hold the refractory. lining24 in position in'the channel-shaped frame 17. Pref-' erably, the lining 24 is'composed ofrefractory bricks or tile, heldtogether'by any suitable-bonding material and supported and vreenforc'ed by the inwardly,'transversely extending ribs 22'and 23 and the'longitudinally extendingribs .13.. The lining abuts againStthe'ribSiIB and 23, thespace between the door frame "and the lining being fllledwith asuitable'heat' insulating material, in-

Steel plates 31. are disposed-onopposite sides in fiat contact with 'the sides-of rthe1door, each plate extendingthe. full lengthlof the door and projecting a short'distanceibeyond. the line of contact between'the flange 29 and'the' side *ofithe' door frame as shown in Fig. -'3.- Plates 31 are suitably fastened .to the metal frameof the'door, as for example by riveting. In 'orde'rto retain the'door' 16 in closed position to'seal-the ends-of the coking chambersllockingbars'33, slidable in guide members 35, integral withthe frame-1'7 may be used. The ends of the locking bars'engage'inclined latches 34'mounted' on'the'buckstays '71. .A

recess or hook '36 is formed on' theframe 217 to,

accommodate the extracting hook of the door removing machine commonly employed 'for this purpose.

Theheating walls 12 are composed'of vertical combustion fiues:39,'the intermediatefiues being defined by side bricks 37. and bricks 38 arranged. at right angles to'the sidebricksand'ha'ving' one.

end rectangular, as indicated at 42, andthe other end' tapered, as indicated at 43, and provided with a shoulder 50. One endof each brick '37 is formed with notch 41, which cooperates with a like notch in the end of an adjacent brick to define a rectangular "recess arranged to snugly receive the rectangular end of brick 38. The other end of'each brick 3'7 is formed with-an oblique face portion 43 andanotch 44 which cooperates with a like face portion on the end of alike'brick' 37to form a seat for the tapered and shouldered end of brick 38. The bricks37 and 38 are arranged as above described with the tapered ends offadjacent bricks 38 facing in opposite direc-' tions and with either the tapered or'rectangular endsbf the bricks 38 in longitudinal alignment in a'djacent heating wallsfacing towards'each other asshownin Fig. 3. v

, The other liner brick 4'7 is provided with an in- 'PWZLZ'CHY extending flange or projection '7, the end of which is formed with a stepped shoulder 58. I'he-rear surface of the extension or projection 5'? consists, of a plane portion 61 and an arcuate orconvex po'rtion 62 similar to the corresponding portions-pf brick 46 with the exception that extension 57 of brick 47 is of greater ex-tentthantheprojection 51 of brick 46.

Anend or intermediate brick 48, designed to closely fit within the space defined by the ends of the extensions- 51and' 57, is-formed with opposite stepped shoulders, 63 complemental-to the shoulders-52 and 58. 'rThe rear surface=of the intermediate brick 48 is arcuate or convexshaped so that it form'sa continuation of theconvex'po'rtions 54 and 62 of lbI'iCkS ;46 and 47 respectively. A jamb brick 65 has the contact-,

ingisurface thereof formed with an arc-shaped or concave.;portion 66 complemental to the :arc formedlbyithe convex portions of bricks 46,47 and 48, and has'theend portions of the rear :surface contiguous to the concave portion defined by verticalplane 67. Concave portion'66 of 'the jambt .brick is arranged to engage-the convex portions of bricks 46, 47 and 48 and theplane portion;6'7 ofzthe jambbrick engages theplane surfaces 55 and .61 of the side bricks "46 and :47 respectively. 5 x

Due to this engagement between the concave portionof .theijambgbrick and-the convex portions of the side or liner brick and the intermediate brick,. the jamb'brick functions todirectly'hold'theside or liner brick 46 and 47 in binding engagement-with the'end brick 48, preventing separation. of the liner brick from the end brick. f V

Bricks 46, '47, and'48 and the jamb gbrick65 are laid vertically in courses which-define the end'structure ofxthe'heating walls eachv side of each endofzthe heating wall ;being formed by alternating "bricks, '46 and '47, disposed directly opposite each'other to'define the opposite sides of each heating wall. In view'of the, complea mentary structure'of the ends of theprojections of bricks 46 and 47, irrespectiveof which brick is to the rightor'left' of therheating wall, the intermediate or end brick :48 ijfits properly between theprojections. 51 'and-5'7'onthe side or.

Flash-or armour plates 68 of channel shape are=disposed to cover the plane; rear'and side surfaces of jambbrick 65. Each flash plateis formecl withoutwardly extending flanges 69- at the side edges thereof. A number of flashplates 68 are used toarmour the: ends of the heating walls, the plates 1 being a preferably arranged with small spaces therebet'wjeen, which permits expansionxof'the metal plates withchanges .in itemperature and eliminates warping-and ,cracking which occurs when-a one-piece metalarmour.

plate is utilized to cover the ends oil-the heating wallsrfIhe flash plates arefh'eld place by" buckstays 71, disposed at opposite sides of the. battery and arranged to contact I with the rear Flange 21 of the door frame is inclined so that it cooperates with the metal plate 72 to provide a luting space-or recess. Flange 19 at the top of the door frame serves to partially cover the top portion of the refractory lining 24. The other top flange 18 is arranged to contact with the lintel plate 73. Flange 18 engages lintel plate 73 to form a luting recess for the top of the door. As hereinafter described, side plates 31 cooperate with flanges 69 on the flash plate to form luting recesses for the sides of the door. Hence, in accordance with. this invention, the door may be luted on all four sides to provide a gas-tightclosure for the ends of the coking chambers.

From the above description,'it will be noted that the brick assembly constituting the ends of the flued heating wall structure is of simple and compact design. The assembly of bricks 46, 47 and 48 in gas-tight engagement is maintained by the jamb brick 65 which engages the rear surfaces of the extensions on the side or liner bricks 46 and 47 and the rear surface of the end brick 48 and holds the side or liner brickin engagement with the end brick. The jamb brick is protected and armoured by the flash plate 68, the flanges 69 of which cooperate with the side plates 31 on the door to provide a luting or sealing space for the door.

It will be further noted that the construction of the brickwork, flash plates, and door is such that substantially the entire surface of the metal flash plates and the metal door frame are exposed to the atmosphere and only a minimum extent of the flanges 69 of the flash plates and the side portions of the door frame extend beyond the luting seal where they are subjected to the high temperatures prevailing in the coking chambers. In view thereof, and further, due to the feature of having a plurality of flash plates armouring each end of each heating wall, the flash plates being arranged in spaced relation to permit contraction and expansion thereof with changes in temperature, warpage and cracking of the flash plates and metal work in the sides of the battery are eliminated. Also, in accordance with this invention, the major portion of the door does not extend into a coking chamber space beyond the luting seal, i. e. where the plates on the sides of the door contact with the flanges on the flash plates, so that carmonaceous substances are not deposited on the major portion of the door, but can form only on the minor portion exposed to conditions within the coking chamber. Hence, the area of the door surface which must of necessity be cleaned of the deposit accruing thereon during the coking operations is materially reduced and a saving in time and labor in the cleaning of the door is effected.

The invention, as hereinabove set forth, is embodied in a particular form of construction, but it is to be understood that it may be variously embodied within the scope of the following claims.
